9.4.2.5 Routing CC and GPIO

Routing the CC lines with a 10-mil trace ensures the needed current for supporting powered Type-C cables through VCONN. For more information on VCONN refer to the Type-C specification. For capacitor GND pin use a 16-mil trace if possible.

Most of the GPIO signals can be fanned out on the top or bottom layer using either a 8-mil trace or a 10-mil trace. The following images highlight how the CC lines and GPIOs are routed out.
